Patent DE-3809869-A1 (DE)
Title: Hydrostatic transmission
Inventor: DEININGER HORST DIPL ING
IPC: F16H61/42
Filed: 1988-03-24
Abstract: To simplify the construction of a hydrostatic transmission featuring pump-and-motor-displacement control, with a variable-displacement pump (1) and at least one variable-displacement motor (4), which has a pump-control device (13) and a motor-control device (25), and in order to integrate the control of the motor displacement in a simple manner into a higher-order control system (2a, 3a, 19), the proposal is to put the pump-control device (13) and the motor-control device (25) in effective connection with one another and to make the degree of the effect dependent on the setting of the displacement of the pump (1). This makes it possible to use a two-position motor as the displacement-controlled motor. <IMAGE>

Patent DE-3904089-A1 (DE)
Inventor: KRIEG GUNTHER PROF DR ING
IPC: G01N21/25
Filed: 1989-02-11
Abstract: The invention relates to the improvement of a method and a device for measuring radiation absorption by a medium in order to achieve and maintain a high measurement accuracy with low drift over a long service period, without the need to replace the components used at fairly short intervals. To achieve the object, it is proposed, according to the method, that radiation flashes of extremely short duration are transmitted through the medium and the radiation pulses received are expanded in time before being further processed. The device is designed in such a way that a radiation source has a flash (11, 12) and that an amplifier (15, 16) which expands the flash pulses received in time is connected to the output of a detector (13, 14). <IMAGE>

Title: Electromagnetic contactor for machinery or air conditioning
Inventor: ICHIMURA YASUO
IPC: H01H1/18
Filed: 1989-03-14
Abstract: An electromagnetic contactor is formed by disposing an inner yoke to oppose at an end to a pole-contacting member provided at an end of an armature in an electromagnet block.  The outer yoke is disposed to oppose at an end to the end of the inner yoke to restrict the displacement of the pole-contacting member and at the other end to a plunger part of the armature perpendicularly and closely to it. A magnetic cylinder is inserted into an axial through-hole of a coil bobbin of the electromagnet block for passing through the plunger part from the side of the other end of the outer yoke. Any leak of magnetic flux due to coil excitation and that of a permanent magnet disposed between the both yokes can be restrained to be the minimum and a highly efficient operation of the contactor can be realised.
Patent DE-3908989-A1 (DE)
IPC: B23P15/14
Filed: 1989-03-18
Abstract: The invention relates to a method of making a gear-change sleeve for manual motor vehicle transmissions. According to the invention, the sleeve is produced in the form of two approximately symmetrical individual parts (1, 2) and is subsequently further-processed, by means of customary joining methods, to form a complete sleeve. In consequence, complete sleeves can be made by pressing and sintering for the first time, by means of comparatively cost-effective powder- metallurgy methods.
